Application filed July 28, 1898. $erial No. 687,113. (No model.)

To aZZ whom it may concern:

Be it known that we, ALBERT STERN and RICHARD MARTIN,si1bjects of the King of Saxony, residing at Dresden, Saxony, Germany,

have invented certain new and useful Improvements in or Relating to Cigarette-Making Machines, (for which application for Letters Patent has been made in Great Britain, No. 1,800, dated the 22d day of January,

1898,) of which the following is a specification.

This invention relates to improvements in cigarette-making machines for manufacturing cigarettes with mouthpieces in which the paper is unwound from a roll, out, and treated both for making the cigarette-tubes and the mouthpieces.

The invention consists in the novel construction, arrangement, and combination of parts,as hereinafter fully described,ill ustrated in the drawings, and pointed out in the appended claims.

In the accompanying drawings, Figure l is a side elevation of the machine constructed according to this invention. Fig. 2 is a plan. 8 is a front elevation of the mechanism for driving the core or mandrel for rolling up papertubes and the cutter forcutting off the paper. Fig. 4 is a rear view of the mechan- 0 ism for holding and transporting the cut off sheet of paper for the paper tubes, as well as for applying the gum or adhesive material. Figs. 5 and 6 show the device for rolling up the paper tube in front elevation and side 5 elevation, respectively. Fig. 7 is a detail view. Figs. 8, 9, and 10 show the device for transporting the finished paper tube in side elevation, front elevation, and rear elevation, respectively. Fig. 11 illustrates the device for rolling up mouthpieces in side elevation, partly in section. Figs. 12 and 13 are detail views of the mandrel for rolling up the mouthpieces in side and front sectional elevations. Fig. 14 shows the gearing for driv- 5 ing said mandrel, and Fig 15 shows the device for operating the cutter.

The whole machine is mounted on a bedplate A,pr0vided with a plate or table B. The various parts are driven from a main shaft C,

to which motion is transmitted from a motor by means of pulleys or toothed wheels and belts or chains or in other suitable manner. To enable the working of the machine and the cooperation of its parts to be better understood, it is best to divide the description of the whole working into three parts roll ing up the paper tube, transporting it to the tobacco-filling device, which latter forms no part of this invention, and therefore will not be described, and finally rolling up the mouth-' pieces, the parts effecting these operations being at the same time fully described.

Rolling up the paper tube-The manufacture of paper tubes from tissue paper or the like is eifected by unrolling paper from a supply-roll and passing it through a guide to the cutter, which cuts off the desired lengths. A clamping device then carries the sheet, of paper out ofi? to a roller, which applies a narrow strip of gum or adhesive material to. one edge of the paper, whereupon the rolling-up mandrel seizes the paper and rolls it into a tube, the gummed edge being strongly compressed by a special device. By lateral movement of the mandrel the finished tube is brought outward in order to be removed by a suitable device from the returning mandrel. The intermittent feeding of the paper from the supply-roll is efiected by rollers l and 2, Figs. 1 and 2, which frictionally engage with a pulley 3, the broad rim of which has a layer of rubber, felt, or similar surface. The movement of the pulley 3 for feeding the paper is effected,according to the example illustrated, by a rod 4, connected at one end to the edge of a sprocket-wheel 5 and adj ustably mounted at the other end in a slot of a lever 6, loose on the shaft 7 of the friction-pulley 3. To this shaft is keyed a pulley 8, having a grooved rim, which cooperates with a brakeblock 9, mounted on the frame by means of a spring for preventinga backward rotation of the friction-pulley 3. The rocking motion communicated to the latter by the rod 4 effects an intermittent advance of the paper, 5 the extent of said advance being capable of being varied by adjusting the rod 4 in the slot of the lever 6 according as it is desired to make shorter or longer paper tubes. The paper passes first througha guide consisting 10o of two plates 10, connected together with a small interval between them, and then, Fig. 3, after a length has been out 01f by a pivoted cutter 13, operated by a rod 14 from a toothed segment 15, the strip is seized by a clamping device consisting of a block 11, Fig. l, with a bracket 12 placed over it and sliding in guides. On the bracket there is a sliding roller 16, resting on a pivoted plate 17. To open and close the clamping device, said plate is raised and lowered by pivoted levers 18 18 18, acted upon by a cam 19,mounted on the driving-shaft O, roller 20, attachedto the lever 18, traveling on said cam. The closed clamping device brings the sheet of paper first to the roller which applies the gum and then to the rolling-up mandrel. To enable it to be moved laterally, the clamping device is arranged in a guide in a fixed part 21, Fig. 4, and connected by a link 22 with a double-armed lever 24, pivoted about a pin 23, a roller 25 on the short arm of said lever engaging with a cam-disk 26 on the driving-shaft C. On a support 28 is arranged the gum-reservoir 29, having a spreading-roller 30. Inordertoapply thegumonlyinauarrow strip at the edge of the paper, there is arranged on the gum-reservoir 29 a bracket 32, pivoted about a pin 31 and provided at the top with a thin plate 33, having a downwardly-bent front edge. At the back of this bracket projects a pin 34, Figs. 2 and 4, under which passes a projection on the connecting-rod 4 during the advance of the latter and strikes said pin, whereby the bracket 32 is caused to turn on its pivot, so that the projection or plate 33 presses the paper against the gumming-roller for a short time. The movement of the clamping device 11 toward the gumreservoir 29 can be regulated by means of a screw 36 in order to provide a more or less wide strip of paper with gum. In its next movement to the opposite side the clamping device 11, Fig. 4, brings the sheet of paper to the rollingup mandrel 37, which is rotated from the driving-shaft O by means of the toothed segment 15 and-the two toothed wheels 38 and 39, Figs. 2 and 3. This mandrel is mounted in the latter wheel 39 by means of a pin 40 engaging in a longitudinal groove in said mandrel, so that it can move in the wheel longitudinally, but cannot rotate. In order to keep it locked for a certain time, a pin 41 engages in a recess in a disk 42, secured to the toothed wheel 39. The withdrawal of the locking-pin is effected by means of levers 43 from the toothed segment 15, a roller 44 on a pivoted arm cooperating therewith, traveling on a projecting are 45 on the segment 15. The pin 41 slides on the disk 42 and is caused to engage in the recess in the disk by the spring 46 in the rotation of the disk. To press the paper against the rollingup mandrel, Figs. 5 and 6, a bar 47, triangular in cross-section, is mounted on a slideblook 49, applied to a disk 48, and pressed down, together with thesaid block, by aspring 50 as soon as the paper has arrived between the rolling-up mandrel and the bar. During this time a spring-controlled plate 51, held in a clamp 52, slides on the paper, and at the moment when the gummed edge of the latter comes into position on the bar 47 pressure is exercised by a bell-crank lever 53, Figs. 5, 6, and 7, one arm of which lies in the path of a projection 54, carried by the disk 48, and when said projection strikes the arm of lever 53 the opposite arm will be forced against the plate 51, which acts to close the gum med seam along its entire length. The raising of the slide 49, Figs. 5 and 6, for the purpose of raising the bar 47 from the mandrel 37 is eifected by means of a roller 57 on a rod 55 engaging with a cam 56. The roller 57 is secured t-oa guide 58, which is guided on a pin 59 of a plu mber-block 60. The advance of the mandrel 37 in a longitudinal direction for thepur pose of delivering the finished paper tube is effected by a cam 61, Fig. 1, and an adjustable lever 63, provided with a friction-roller in contact with the cam and connected by a ball-and-socket joint 64 with the mandrel. Springs 65 and 66 return the parts to their position of rest.

Transport of the paper tube.The transporting device serves to receive the finished paper tube from the mandrel 37 and to bring it to the tobacco-filling device, where the charge of tobacco is introduced into the empty tube. Then the transport device brings the filled tube to the mouthpiece-rolling device, the mouthpiece being placed into the filled paper tube. Finally the transporting device opens and releases the finished cigarette. On the driving-shaft O, Figs. 1 and 8, is mounted a cam 67, in contact with which is a roller 68 at the end of 'a double-armed lever 70, pivoted about a pin 69 and engaging at its other end, by means of an arm 71, with a part 72, moving the latter laterally in its dovetailed guide 73, Fig. 9, on the table B, the lever 70 being opposed by a spring attached to the part 72 and having a tendency to return the latter into its original position. The part "2 supports all the other parts of the transport device by means of a spindle 74, secured to the part 72. The lateral movement of the device serves to transfer the paper tube from the paper-tube-making device to the tobaccofilling device. The reciprocation of the latter toward and from the mouthpiece-rolling apparatus is efiected by a second donble-armed lever 75, pivoted to the spindle 74 and having a friction or other roller 77 in contact with a cam 76 on the driving-shaft O, by which it is operated. This lever oscillates in a recess 78 of the table B, Figs. 9 and 10. The lever carries at its upper end a head in the shape of pivoted tongs 79, the jaws of which are connected together byconnecting-pieces (socketandpin) in the casing 80 and are opened and closed by a pair of pivoted links 81. This opening and closing of thejaws 79 by means of the links 81 is efiected by a two-part rod,

ICC

the upper part 83 of which is guided in holes in the projections 84., the lower bifurcated end sliding by means of a pin 85 in a slotted guide 86 at the top of the lower part of the rod 87. This rod is guided in a hole in the spindle 74 and is connected at the bottom with a lever 88, provided with a roller 89, traveling on a cam on the main shaft 0. This sectioning of the rod for opening and closing the jaws 79 and the connection of its parts by means of a slide is necessary, as the upper part 83 must participate in the oscillations of the lever 75, while the lower part 87 is only allowed to have a vertical movement in order to produce a sharp blow against the small cam 90 on the shaft 0. The arrangement described of the separate driving parts of the transport device on the main driving-shaft is such that in the position of rest the tongs are near the paper-tube-making device, with the jaws open, the finished tube being seized by the jaws closing upon it and drawn off the mandrel and brought to the groove of the tobacco-rolling apparatus by a lateral movement of the whole device, where it is filled with tobacco and carried by the return movement of the transport device to the mouthpiece-rolling apparatus in order finally to insert the mouthpiece and to release the finished cigarette by opening the jaws, which then return into their original position.

Forming the m0uthpt'eces.For this purpose a piece of paper of suitable length is cut oif from a roll of paper in an oblique manner, so as to obtain. a point with which the rolling begins. This is effected by a slotted former on which moves a plate for clamping or holding the paper. The finished mouthpiece is removed from the former by means of a ring and inserted into the filled paper tube and held to the last by the sliding plate, so that it cannot unroli before being introduced into the paper tube. The rolling-up former 91, Figs. 11 and 12, into the slot 92 of which the paper is introduced by a device hereinafter described, is surrounded by a sleeve 93, having double slots 94, Fig. 13, and is carried in a partially-hollow shaft 95, in the rotation of which it is caused to participate by a pin 96, guided in a double slot 97 in the shaft 95, thus preventing a lateral movement of the core during the movement of the shaft in its longitudinal direction. The shaft 95, with the former 91, is caused to rotate at a great speed from the main driving-shaft O by means of a toothed, segment 98 and toothed gearing 99, the former 91 rolling up the paper introduced into its slot 92, a spring-coi'itrolled plate 100, Figs. 12 and 13, in contact with the former pressing the paper and maintaining the roiledup mouthpiece in shape. The shaft passes loosely through the upper toothed wheel 99 and is connected to it by a tooth-shaped projection 102 engaging with a longitudinal groove 101 in it, so as to enable the shaft 95 to move freely in a longitudinal direction. To stop and hold the shaft 95 stationary at a desired moment, a tooth 105, Fig. 14, engages with a recess 103 of a disk-shaped projection 104 of the toothed wheel 99, said tooth 105 being secured to a lever 106, which is intermittently raised by its roller 108 coming in contact with an are or cam 107 of the toothed segment 98 and slides along the disk 101 and is caused by the spring 110 to spring into the recess 103 when it comes opposite to it. The longitudinal movement of the shaft 95 for removing the mouthpiece from the former 91 and inserting it into the paper tube filled with tobacco is effected by a double-armed lever 111 adjustable in guide-slots, a friction-roller 112 on the lower end of said lever sliding on a cam 113 on the main shaft 0, the upper end of the lever 111 being connected by a ball-and-socket joint 114 with the shaft 95. The latter is thus intermittently advanced and retracted. Consequently the circular front part which surrounds the former 91, Fig. 11, removes the mouthpiece and pushes it out of the sleeve 93.

A very important feature of the device is the feeding and cutting off of the paper from the main roll, which is efiected only when the mouthpiece has been made by means of two cutters 123 and 12 1, placed at an acute angle to each other in such manner that one cutter cuts off the finished mouthpiece in a straight line, while the other cutter, placed obliquely, cuts the paper obliquely for the next monthpiece, so that a triangular piece of paper is cutout and falls out from the machine. The paper is arranged in a movable guide 115, Fig. 2, covered by a fixed plate 116, and is caused in a suitable mannerin this case by a stop 117 on the oscillating part 75 of'the transport deviceto take part in the movement until a pin or rod 119 strikes a projection 120 of a movable clamping-bar 121, Whereby the paper strip, which was held fast up to that moment,becomes released,said strip having been already introduced into the slot 92 of the former 91 and rolled up several times. The guide 115 is withdrawn by a spring 118 and returns empty and only at the end of its travel again clamps the strip. The two outters 123 and 124, connected by an angle-iron 122, then descend simultaneously and cut off the paper from the mouthpiece in the manner described. The lowering of the cutters, one (123, Fig. 15) of which is pivoted to the shaft 125, is effected by levers 126, actuated by a cam 127 acting ona friction-roller128 in contact with it.

The rest of the parts shown in the drawings serve for producing the tobacco rope and introducing it into the paper tube. This part of the machine will be only described as far as is required for the understanding of the whole machine, since the same work could be effected by other devices.

Tobacco is supplied to the angle or pressing device 131 by endless bands 129, passing from a cam 133 on the main shaft. The tobacco cut off is seized by a piece of sheet metal 135, bent at an angle and brought to the discharge groove or opening D, Fig. 2,and pressed into said groove by a device 137, driven from a sprocket-wheel 138 by means of a projection 139 on the latter, and then pushed into the paper tube placed by a rod 140. The whole device for rolling and compressing the tobacco is mounted on a movable plate 141 and is operated by it.

The rod 140 for pushing the tobacco forward is operated by a rod 142, which is pivotally connected at one end to the chain-Wheel 5 and at the other end to the slide-block 144. In the slide-block 144 there is arranged a rod 145, which when advancing carries with it the rod 140. For this purpose there is arranged on the rod 145 a part consisting of two cam-faces adapted to come in contact with the roller 147, and thus cause the rod 145 to advance, which rod then engages with the pin 148 of the rod 140 and causes the latter to participate in its movement until the part 146 strikes a roller 149 and draws the rod 145 back and releases the rod 140. The latter is then returned by a spring into its original position. The sprocket-wheel 5 is driven by a chain 143 from the driving-shaft G, on which is mounted the chain-pinion 150. The shaft 0 is at right angles to the main driving-shaft O and coupled with it by bevel-wheels 151.
